pdp-10 n. programmed data processor model 10 the machine that made
   timesharing real. it looms large in hacker folklore because of its
   adoption in the mid-1970s by many university computing facilities and
   research labs, including the mit ai lab, stanford, and cmu. some aspects
   of the instruction set most notably the bit-field instructions are
   still considered unsurpassed. the 10 was eventually eclipsed by the vax
   machines descendants of the pdp-11 when dec recognized that the 10
   and vax product lines were competing with each other and decided to
   concentrate its software development effort on the more profitable vax.
   the machine was finally dropped from dec's line in 1983, following the
   failure of the jupiter project at dec to build a viable new model. some
   attempts by other companies to market clones came to nothing; see
   foonly and mars. this event spelled the doom of its and the
   technical cultures that had spawned the original jargon file, but by
   mid-1991 it had become something of a badge of honorable old-timerhood
   among hackers to have cut one's teeth on a pdp-10. see tops-10,

        most notably the bit-field instructions are still considered
        unsurpassed.
